Thanks for responding. I had the original manual that would be a solution. As I don't, model numbers help.

Are you saying "smarts" are in the wall wart, not the cradle?

The best way to tell if a charger is "smart" is to RTFM (Read The Freaking Manual). The manual will tell you if you can just leave the battery on the charger or if you need to not charge more than a certain number of hours. My manual tells me that I shouldn't charge the battery with the supplied charger (NC-88B) for more than 10 hours. I think the new radios all come with a charging cradle but the actual charger that you plug into it is still only a 10 hour charger that you need to disconnect the radio from when the battery is fully charged. Yaesu does sell the VAC-370B Rapid Charger that is smart and will not overcharge the battery. With that you can leave the radio in it all the time and it will stay topped-off without overcharging.

I leave my radio pugged into my charger and have the charger plugged into a timer so it comes on and charges the radio for 10 minutes every day. That keeps it charged without overcharging the battery.

How does one know whether or not the charger is "smart"?

There is no need to completely discharge the battery. NiMH batteries do not need that. Even the old NiCad batteries only had that problem if they were habitually discharged to the same capacity repeatedly.



The one thing you can do that will harm the FT-60 battery is to overcharge it. If the charger that came with it is not a smart charger make sure not to let disconnect it after a few hours or when the battery starts getting very warm. I think the FT-60 comes with a smart charger now. Such was not the case when I bought mine years ago.

My answer is no. That was the case with NiCad batteries because they had a memory. Today's batteries aren't NiCad and they don't have that memory effect. When your battery is low, charge it.

I am sorry if I overlooked this answer somewhere else. I just purchased my first ft-60 and wondered if it was best to let the battery "completely drain" before recharging, and just re-charge when the battery indicator shows low? Someone mentioned letting it "completely drain" before re-charging - left it on for about 20 minutes after the low battery indicator started flashing . I just want to do what is best for the battery. Also, approx. what low voltage reading will trigger the low battery indicator? Thank you. -Scott
